CAHABA COAL FIELD: LOLLEY BASIN. 85 
Wilderness church, the Reneau place, Columbus Harper’s, 
and the William Lacey farm. 
The Brierfield, Blocton and maeuian Railroad fol- 
lows close along the eastern and northern boundaries of 
this basin, joining the Birmingham Mineral at Piney Woods 
Station and Gurnee Station, there connecting with Blocton 
and Bessemer and Birmingham, and the Birmingham Min- 
eral Railroad to Helena and Birmingham ; the south end of 
said road connects with the Hast Tennessee, Virginia and 
Georgia Railroad at a point one mile southwest of Monte- 
vallo. P 
The length of the Lolley basin is five and 4 quarter miles 
by an average width of three and fourteen hundredths 
miles; its surface area is sixteen and a half square miles. 
The amount of workable coal it contains, in seams of two 
feet and upwards in thickness, and within a vertical depth 
of 4,400 feet, is 357,000,000 tons (of 2,000 pounds), This 
computation makes no allowance for loss in pillars, or waste 
in mining. 
The lowest workable seam outcropping in this basin is 
the Gholson; it outcrops in a few places along the Piney 
Woods fault, but in most places along this fault the seam 
is down in the fault. I have made a slight effort to cut its 
outcrop in that locality, but lack of time prevented me giv- 
ing it a thorough test along the outcrop. This is an excel-~ 
lent seam with a good sandstone roof, in places having a 
thin layer of compact slate at the top of it; and it will aver- 
age in thickness, in my estimation, four feet of good coal 
without slate partings. The next seam above this and out- 
cropping farther south, is the Little Pittsburgh, then above 
this and underlying the Conglomerate, is the Thompson or 
Conglomerate seam, then still farther southward is the out- 
crop of the Helena seam, of which the following is a meas- 
ured section :
